NVMe and SSD are both types of solid state drives (SSDs), but NVMe drives use a newer and faster interface called PCI Express (PCIe) to connect to the motherboard, whereas traditional SSDs use the older SATA interface. NVMe drives can offer faster read and write speeds, lower latency, and higher bandwidth than SATA SSDs.
In terms of gaming, NVMe drives can potentially offer faster load times for games and improved performance in certain games that are heavily reliant on fast storage. However, the difference may not be noticeable in all games and the overall gaming experience may not be significantly impacted by the choice of storage.
If you are building a new PC, it is generally recommended to go with NVMe drives, as they are becoming increasingly more affordable and offer more performance potential than SATA SSDs.
